Decklink: Make input/output modules build on OSX The Decklink SDK has platform-specific implementations for various calls which return strings. Add some portability macros to properly handle those calls and then normalize the result down to a C char * as we would typically see in VLC.

decklink: fix compilation on Windows DeckLinkAPIDispatch.cpp doesn't exist on Windows and CreateDeckLinkIteratorInstance() too. Instead we should use CoCreateInstance(). The strings are BSTR. Use the proper enum values where appropriate. Some types are different between Windows and Linux/macOS.

decklink: allow building on Windows We don't have any system specific calls in our code. It seems the decklink_str_t only needs special handling on macOS. It's a char* on Linux and Windows.
